Abstract: A sealed package includes top and bottom portions, and a main portion between the top and bottom portions and including side wall portions. The main portion is divided from the top and bottom portions respectively by top and bottom peripheral outlines extending transversally to a longitudinal direction. The top and bottom peripheral outlines each have a broken-line shape and are formed by plural joined contour edges. The top/bottom portion includes a quadrilateral top/bottom panel orthogonal to the longitudinal direction and delimited by the top/bottom peripheral outline. The bottom panel area differs from the area of a top quadrilateral obtained by projecting, along the longitudinal direction, the top panel on a reference plane parallel to the bottom panel, crossing the package and containing at least one of the contour edges of the top peripheral outline.

Abstract: There is described a packaging blank comprising a first longitudinal boundary edge, a second longitudinal boundary edge, a first transversal boundary edge and a second transversal boundary edge. The packaging blank also comprises a top crease pattern having a first transversal crease line and a second transversal crease line and a bottom crease pattern having a third transversal crease line and a fourth transversal crease line. The second transversal crease line is closer to the first longitudinal boundary edge and/or to the second longitudinal boundary edge than the first transversal crease line and/or the fourth transversal crease line is closer to the first longitudinal boundary edge and/or the second longitudinal boundary edge than the third transversal crease line.

Abstract: A sheet packaging material for producing a sealed package with a pourable food product; the packaging material has a quadrangular configuration with two boundary edges parallel to a longitudinal direction and two other boundary edges parallel to a transversal direction orthogonal to the longitudinal direction; the packaging material comprises two transversal crease lines extending transversally to the longitudinal direction and dividing the packaging material into: a bottom region containing a bottom crease pattern and configured to form a bottom portion of the package; a top region containing a top crease pattern and configured to form a top portion of the package; and an intermediate region contained between the transversal crease lines and designed to form a main portion of the package having a plurality of side wall portions; the intermediate region further comprises a plurality of V-shaped crease lines having respective vertices located on or adjacent to the transversal crease lines and at given points t

Abstract: A sheet packaging material for producing a sealed package comprises two first boundary edges parallel to a longitudinal direction and two second boundary edges parallel to a transversal direction orthogonal to the longitudinal direction. The sheet packaging material includes at least a bottom transversal crease line including a bottom central portion, a bottom end portion and a bottom side portion. The sheet packaging material includes a pair of slanted crease lines inclined relative to both the longitudinal and transverse directions. The slanted crease lines have first ends pointing to one of the second boundary edges and second ends pointing to a continuous line parallel to the transversal direction and including the bottom central portion and the bottom end portion. The slanted crease lines delimit, with the bottom side portion, a flap area of the sheet packaging material designed to form at least part of a lateral flap of the package.

Abstract: A sealed package containing a pourable food product and comprising a bottom portion, a top portion and a main portion interposed between the bottom portion and top portion and including a plurality of side wall portions; the main portion is divided from the bottom portion and said top portion respectively by a bottom peripheral outline and a top peripheral outline extending transversally with respect to a longitudinal direction; each of the bottom peripheral outline and the top peripheral outline has a broken-line shape and is formed by a plurality of contour edges joined to each other; the bottom portion comprises a quadrilateral bottom panel delimited by the bottom peripheral outline and extending orthogonal to the longitudinal direction; the top portion comprises a quadrilateral top panel delimited by the top peripheral outline and extending transversally to the longitudinal direction; the area of the bottom panel is different from the area of a top quadrilateral obtained by projecting, along the longitudi

Abstract: A method for producing a sealed package for a product may include: providing a sheet packaging material having a crease pattern with a first transverse crease line, a second transverse crease line, and a plurality of further crease lines interposed between the first and second transverse crease lines, the further crease lines extending transversely to the first and second transverse crease lines; obtaining a sealed preliminary packaging unit from the sheet packaging material, the sealed preliminary packaging unit having a preset inner volume and containing the product; exerting a forming action on the sealed preliminary packaging unit so as to fold the sheet packaging material defining the sealed preliminary packaging unit and obtain a package therefrom. During the step of obtaining the sealed preliminary packaging unit, the sheet packaging material may be processed without being folded along the further crease lines.
